This company puts fast-food yummies in a whole lot of tummies. YUM! Brands is the largest fast-food operator in the world in terms of number of locations, with more than 42,000 outlets in some 130 countries. (It trails only hamburger giant McDonald's in sales.) The company's flagship chains include #1 chicken fryer KFC (with more than 14,500 units), top pizza joint Pizza Hut (more than 13,700), and quick-service Mexican leader Taco Bell (more than 6,400). YUM! sold the Long John Silver's seafood chain, along with several hundred A&W root beer and burger stands to two separate buyers in late 2011. In 2016 YUM! Brands spun off its Chinese operations into a separately traded public company.
